The road through the Clue d’Aiglun is a very scenic drive following a narrow ledge cut into the rock. It’s one of the French balcony roads. The road (D10) runs as a single track road along the mountainside for some distance with nowhere to pass another vehicle. Here one says a prayer that nobody is coming towards you until the road widens a kilometre further westward.
This stretch of road, located in the Alpes-de-Haute-Provence department in the Provence-Alpes-Côte d'Azur region of southeastern France, should not be attempted by those who don't know how to reverse! The road within the gorges (2km. long, 200 to 400 m. high) is continually featured in magazine and television programs internationally linked to driving in Les Alpes Maritimes. There are a few tunnels and galleries along the way. The road runs deep into the pine-covered mountainsides around where water flowing down from the Alpes-Maritimes has sculpted countless grottoes and rock passages in the white limestone.
This part of the D10 road is a stage in some famous car rallyes. Rally d’Antibes or Grasse Alpin go through this clue. The Clue d'Aiglun is also the starting point for some excellent walking. Both (Montagne de Charamel and Mt St Martin 1.257m) provide excellent views into the Clue. There are some narrow sections totally impassable for 2 cars at the same time.
This road is one of the most famous balcony roads in France. A balcony road is a hair-raising lane cut into the sides of sheer cliffs. It’s a kind of road not for those who fear heights. There is little room for error on these roads. It’s normal for your palms to sweat looking at those photos, imagine what it must have been like before the barriers. The single track road has been blasted out of the mountainside and run underneath overhanging cliffs through blind bends prior to entering a rock tunnel that exits directly onto the approach to the Pont d'Aiglun some 3/400 feet above the spellbindingly beautiful mountain 'snow melt' river River Esteron some 3/400 feet below the bridge. The road, where the Estéron river flowing from the Alpes-Maritimes has carved out canyons and rock passages in the white limestone, follows a series of gorges in the hills north of Cannes, in the Haute Provence.
